Under the instruction of above-mentioned theoretical results, in the thesis chapter 10, the strongly electron-withdrawing anion, C_5O_5~(2-)[dianion of croconic acid (4,5-dihydroxycyclopent-4- ene-1,2,3-trione)], was chosen as the chelator to coordinate with boron to form lithium salt, which will yield high ionic conductivity solutions, and exhibit wide electrochemical stability windows and high thermal stability. As described in the chapter, two new lithium salts containing C_5O_5~(2-), lithium bisborate and its novel derivative, lithium borate for Li-ion battery electrolytes were synthesized.

First,the content of surfactant should be more than 18 percent and the content of anion surfactant should be kept in proper proportion to the content of nonionic surfactant. Second,the content of zinc naphthenate should be kept in directly proportional to the content of other surfactant. Third,the content of rosin shouldnt too higher and the content of oleic acid should be kept in directly proportional to the content of rosin. Fourth,the content of water should be kept in a low level (less than 8%);otherwise emulsifier oil will delaminate. In addition,the requisite content of sodium heavy alkyl benzene sulfonate is higher than petroleum sulfonate.

试验表明在以松香、重烷磺酸钠、石油磺酸钠为主要乳化剂时，要获得优良的乳化液，需满足以下几个条件：(1)需在乳化油配方中加入适量的乳化剂，且其中阴离子乳化剂总量与非离子乳化剂总量的应保持适当的比例；(2)乳化油中环烷酸锌的量与其它乳化剂总量要保持正比关系；(3)乳化油中松香的量不易过大，且油酸的加入量应与松香量成正比；(4)乳化油中水分含量不易过高(一般不能大于8％)，过高时稳定性不好，易分层。
